Mechanics, Shape, And Programmability In Soft Matter Systems: From Fluid Membranes To Spring And Droplet Networks, Tao Zhang Jan 2015

Mechanics, Shape, And Programmability In Soft Matter Systems: From Fluid Membranes To Spring And Droplet Networks, Tao Zhang

Dissertations - ALL

This thesis analyzes three different soft matter systems---membranes, polymers, and droplets---to answer questions about shape, mechanics, and programmability.

For membranes, my collaborators and I have developed a theoretical model of endocytosis in yeast. Endocytosis is the process by which a cell membrane deforms to surround extracellular material to draw it into the cell. Endocytosis in yeast involves clathrin, actin, and Bar proteins. Our model breaks up the process into three stages: (i) initiation, where clathrin interacts with the cell membrane via adaptor proteins, (ii) elongation, where the membrane is then further deformed by polymerizing actin filaments, followed by (iii) pinch-off. …


Geometry Dependence Of The Sign Problem In Quantum Monte Carlo Simulations, V. Iglovikov, Ehsan Khatami, R. Scalettar Jan 2015

Geometry Dependence Of The Sign Problem In Quantum Monte Carlo Simulations, V. Iglovikov, Ehsan Khatami, R. Scalettar

Faculty Publications

The sign problem is the fundamental limitation to quantum Monte Carlo simulations of the statistical mechanics of interacting fermions. Determinant quantum Monte Carlo (DQMC) is one of the leading methods to study lattice fermions, such as the Hubbard Hamiltonian, which describe strongly correlated phenomena including magnetism, metal-insulator transitions, and possibly exotic superconductivity. Here, we provide a comprehensive dataset on the geometry dependence of the DQMC sign problem for different densities, interaction strengths, temperatures, and spatial lattice sizes. We supplement these data with several observations concerning general trends in the data, including the dependence on spatial volume and how this can …


Finite-Temperature Superconducting Correlations Of The Hubbard Model, Ehsan Khatami, Richard Scalettar, Rajiv Singh Jan 2015

Finite-Temperature Superconducting Correlations Of The Hubbard Model, Ehsan Khatami, Richard Scalettar, Rajiv Singh

Faculty Publications

We utilize numerical linked-cluster expansions (NLCEs) and the determinantal quantum Monte Carlo algorithm to study pairing correlations in the square-lattice Hubbard model. To benchmark the NLCE, we first locate the finite-temperature phase transition of the attractive model to a superconducting state away from half filling. We then explore the superconducting properties of the repulsive model for the d-wave and extended s-wave pairing symmetries. The pairing structure factor shows a strong tendency to d-wave pairing and peaks at an interaction strength comparable to the bandwidth. The extended s-wave structure factor and correlation length are larger at higher temperatures but clearly saturate …
